I One of the objects of my invention is to provide a show viseparticularly adapted for shoe lasts of various types and sizes to facilitate thehand sewing operations. 7

Another object ofmy invention is to provide a vise and bench. clamp including pro vision for positioning a detachable shoe last whereby the shoe'and particularly the heel portion may be firmly held in position to enable the operator to perform the hand sewing operations onthe sole and shoe upper.

A further object of my invention is to construct a combined vise and clainp'which will be simple, easilymanufactured at a comparam tively low cost, efficient and practical, strong,

durable and capable of use'on any type of work bench either in the factory 'orindi vidual shop. 7 i f To enable others skilled in the art to more fully comprehendthe underlying features of 7 my invention, reference is had to the accomspecification in which Fig. '1' is a front view.-
